2.64V threshold supervisor for a single rail
The TPS3809L30DBVT is a Texas Instruments simple reset/power-on reset IC monitoring a single voltage rail with a threshold of 2.64V. The active-low, push-pull output asserts reset when the monitored supply drops below that threshold and holds it for a minimum of 120ms after the rail recovers. This part is typically specified by hardware engineers who need a clean, deterministic reset pulse for a 3.3V or 3.0V microcontroller, FPGA, or SoC without extra features like watchdog or manual reset.
